Key Specifications

Main Features & Highlights

• 70°C Constant Temperature Heating: Instead of blasting your food with high heat like a traditional microwave—which often dries out meats and leaves cold spots—this lunch box maintains a gentle, constant 70°C holding temperature. It slowly and evenly warms your food, locking in original flavors, nutrients, and moisture.

• Premium SUS304 Stainless Steel Inner Pot: The interior food tray is crafted entirely from food-grade 304 stainless steel. It is highly resistant to corrosion, non-reactive with acidic foods, incredibly durable, and completely safe for daily food storage and heating.

• Convenient Waterless Heating System: Unlike older models that require you to pour water into the base to create steam, the SF-1513 features a dry-heating system. You simply plug it directly into a wall outlet to begin warming up your food without any messy water setups.

• Removable Pot for Easy Cleanup: The stainless steel food compartment lifts entirely out of the outer heating shell. This lets you store the tray in the fridge overnight, pack it in the morning, and rinse it out easily in the sink or dishwasher after eating.

• Leak-Resistant Silicone Seal: The lid is fitted with a food-grade silicone sealing ring that creates an airtight barrier. This keeps your meal fresh, traps heat inside during operation, and guards against accidental spills or leaks in your bag during travel.

• Whisper-Quiet Operation: The internal element heats up completely silently. It emits no loud boiling noises, buzzing, or heavy steam clouds, allowing you to seamlessly heat your lunch in a quiet office cubicle or library without distracting others.
